UV resin

For several years now, filament-based plastic printers have ruled the hobbyist market, with a new iteration on squirting plastic appearing on Kickstarter every week. SLA printers, with their higher resolution and historically higher price for raw materials, have sat in the background, waiting for their time to come.

Now, with the Sedgwick printer now available on Kickstarter, we may finally be seeing some resin printers make their way into hackerspaces and workshops the world over. Instead of other DLP projector-based resin printer where projector light shines up through the resin tank, the creator of the Sedgwick, [Ron Light] is doing things the old-fashioned way: shining the projector down onto the surface of the resin. He says it’s a simpler method, and given he’s able to ship a Sedgwick kit minus the projector for $600, he might be on to something.

There are a few other resin printers coming on the scene – the LittleSLA will soon see its own Kickstarter, the mUVe 1 is already shipping, and over on Hackaday Projects, the OpenExposer project is coming along nicely. All very good news for anyone who wants higher quality prints easily.

If you’re playing along with Twitch Plays Pokemon, you might as well do it the right way: with the smallest Game Boy ever, the Game Boy Micro. [Anton] needed a battery replacement for this awesome, discontinued, and still inexplicably expensive console and found one in a rechargeable 9V Lithium battery. You get two replacement cells out of each 9V battery, and a bit more capacity as well.

Every garden needs garden lights, right? What does every garden light need? A robot, of course. These quadruped “Toro-bots” react to passersby by brightening the light or moving out of the way. It’s supposed to be for a garden that takes care of itself, but we’re struggling to figure out how lights will do that.

Flexiable 3D prints are all the rage and now resin 3D printers are joining the fray. The folks at Maker Juice have introduced SubFlex, a flexible UV-curing resin. The usual resins, while very strong, are rock solid. The new SubFlex flexible resins are very bendable in thin sections and in thicker pieces something like hard rubber. We’re thinking custom tank treads.
